Jennifer Saunders stars in a spellbinding adaptation of David Walliams’ novel Grandpa's Great Escape about a former spitfire pilot and his grandson

A star-studded adaptation of David Walliams’ much-loved children’s novel Grandpa’s Great Escape is airing this New Year. It centres on young Jack (Kit Connor) and his Grandpa (Sir Tom Courtenay), who was a World War Two pilot but now suffers from Alzheimer’s disease.

Jack’s dad, played by David, sends Grandpa to live in chilling old people’s home Twilight Towers, run by the terrifying Miss Dandy (Jennifer Saunders). But the elderly war hero makes a bid a freedom with Jack’s help. Will Grandpa get to fly one of his beloved spitfires again?

Here, David Walliams and Jennifer Saunders tells TV Times about Grandpa’s Great Escape, which is on BBC1 on New Year's Day at 6.55pm…

TV Times: What was your inspiration for the story of Grandpa, David?

David Walliams: “A few years ago there was a veteran soldier in the news who escaped from an old people’s home to go to a reunion with his friends for the anniversary of the Normandy landings. I was intrigued by that idea of escaping - although he’d really just walked out of the door! - and I thought about The Great Escape. I used to love watching old war movies with my dad and I wanted to capture the spirit of those films. But I also remembered how I loved spending time with my grandparents. I had a great connection to them as Jack does with Grandpa.”

TVT: Did you always want to get Sir Tom and Jennifer involved?

DW “Definitely; they are heroes of mine. Tom is a legendary actor and I love Jennifer and have had the pleasure of working with her before. I was chuffed they both agreed, I feel very lucky.” Jennifer Saunders: “It has been completely lovely doing Grandpa's Great Escape. I did The Boy in the Dress with David before and that was such good fun. He writes such great, well-drawn characters and although they are kids’ books, they deal with grown up issues. They are also very funny.”

TVT: What can you tell us about Miss Dandy Jennifer?

JS “It’s a joy playing Miss Dandy with this giant bosom, which David thought was mine and was disappointed when I took it off! It is a cracking character and I loved the book illustration and wanted to make her really mad-looking. She’s a nasty psychopath with no love in her. It was great filming in a creepy, dilapidated house that was perfect for Twilight Towers.”

TVT: Does it feel lovely to have been part of the Christmas TV schedule for several years in a row David?

DW “I love it because there’s not much like this on television and it’s just great being part of Christmas. When you were a kid, it’s where all the most-loved performers were in all those Christmas specials of yesteryear like The Morecambe & Wise Show and The Two Ronnies. I just love sitting watching Christmas television stuffed full of Stilton!”
